‘Rur’ is the Norwegian word for barnacles, which are related to crabs and lobsters. These little fellas have a very interesting life. Their backs are attached to a rock (or a ship), they can’t leave their shell and the only way they can eat is to filter the water for plankton. This makes it very hard for reproduction. Most varieties are hermaphroditic but self fertilizeation is very rare. To reproduce, these little fellas extend their hello up to 15 cm to the next barnacle. They are very impressive creatures, considering they average about 1 cm in length themselves.
